-7/9s Or -5s Garretts

[vspecIInur]

For the price it wouldn't be I guess just to chase 15-20kw..Probably wouldn't even notice it. Will find other ways for further response

Hmm maybe if I go -9's from N1's I can get my 400kw

do u have a build thread on your setup as I'm keen to learn more about -9s?

What are u making with these snails?

sorry nathan - just realised that u are running n1's & not -9s so my above question doesnt apply

I'm running -9s buddy what info would you like?? PM me if you want

Tossing up between -5's or -9's mate?

^Have a friend running GT-SS at 310rwkw @ 18psi (RPM dyno) approx 90-92% inj duty cycle he said. Car has been tracked many times. Fuel system and AFMs are stock.

I have the tendency to go down the same route - retain stock fuel system and AFMs

But I'm concerned about the high injector duty cycle as my car unlike his will see some street and hills use with different temperatures and varying loads.

I also have -9, RPM cam gears, stock dumps, Mine's front pipe, 3" test pipe, 3.5" Tomei Ti catback and PFC.

So all in all, is 90% injector duty considered safe? Accounting for any spikes that may occur.

I know my friend's car is a pretty good example of it's reliability at that level, but would just like some opinions with other guys running -9's who run the car on the street and track as well.

Well what captured my attention is 350kw from -9s...what does it take in terms of boost level and supporting mods to get to this number on 98 as I don't want to run e85?

Hi Nick (levinboy) - what power are u making with your setup?

I'm making 350kw on 98 pump

Full boost at 3800rpm lower depending on weather, 22psi

Built engine still 2.6

Id1000s, Nismo fuel pump

[Mick_o]

Will hopefully have some -9 and E85 results tomorrow

The old mans car is due out of unigroup tomorrow

please share the results - would luv to see some numbers on the outcome

[Mick_o]

Will do mate

I'd say, once again, attention to detail on the setup is where the better results are. Big, size matched exhausts blah blah.

Got a sheet Nick?

[levinboy]

Here is dyno sheet

Tuned for response, hence the drop up top and my cat mainly being restrictive

Will be retuning it soon with new cat soon

[Piggaz]

"Single cell"?

[levinboy]

"Single cell"?

A proper cat, the "race" cat comes out only for the track

[gtr jet]

I run -7's with a shitty exhaust and stock afm's. With id1000's and a walbro 400 fuel pump I make 325kw on 20psi with E85. If I fix my exhaust and chuck some bigger afm's on I'd probably crack 350kw.

It'd be much easier to do it with -9's and I don't think there would be much more lag involved.

paul - u should overlay your graph with nicks, i wonder what the difference would be in response & what revs u have full boost

Ill have a play tonight. Need a calculator and a graph to doodle on.

Fkn speed. Put it in RPM farken!
